[0002] The mined ore needs to be processed. Ore processing includes mechanical processing and chemical processing. Mechanical processing refers to the use of mechanical equipment to process ore. Commonly used mechanical equipment includes crushers, screeners, mills, etc. In the process of mechanical processing, the ore is continuously crushed, screened, milled, etc. to change the ore into the required particle size and form, which provides a basis for subsequent chemical processing and physical processing. For the ore that has just been mined, jaw crushers are generally used to crush the ore. However, there are still the following disadvantages when crushing the ore with a jaw crusher:

[0003] When the existing jaw crusher is crushing ore, the ore often slips and gets stuck between the movable jaw and the static jaw of the jaw crusher.

[0033] Embodiment 1

[0034] As attached Figure 1-Figure 5The ore crushing device with a feeding mechanism shown in the figure has a jaw crusher body 110 fixedly installed on the upper end of the outer wall of the mounting base 100, a feed port 120 is opened inside the jaw crusher body 110, a mounting seat 201 is welded symmetrically on the upper end of the outer wall of the mounting base 100, a connecting rod 200 is fixedly installed on the upper end of the outer wall of the two mounting seats 201, and the side walls of the left and right connecting rods 200 are slidably connected with sliding sleeves 210 at the same time, and connecting frames 220 are fixedly installed on the opposite ends of the side walls of the two sliding sleeves 210, and a plurality of knocking rods 300 are linearly arranged at the lower end of the outer wall of the connecting frame 220. The ore enters the jaw crusher body 110 from the feed port 120, and the ore is crushed by the jaw crusher body 110. The knocking rod 300 that moves downward knocks and squeezes the ore stuck in the jaw crusher body 110, thereby increasing the friction between the ore and the static jaw in the jaw crusher body 110, so that the ore can be smoothly squeezed and crushed by the jaw crusher body 110. A support column 101 is fixedly installed at the lower end of the outer wall of the mounting base 100, and a drop opening 121 that is connected to the inside of the jaw crusher body 110 is fixedly installed at the lower end of the outer wall of the mounting base 100. The squeezed and crushed ore can be discharged to the outside of the device through the drop opening 121. A movable jaw assembly 130 is installed inside the jaw crusher body 110, and a drive shaft 140 is rotatably connected to the upper end of the outer wall of the jaw crusher body 110. The drive shaft 140 is rotatably connected to the movable jaw assembly 130.

The right side of the outer wall of the intermediate block 430 is rotatably connected with the upper end of the outer wall of the crank 420. The rotation of the driving wheel 410 drives the crank 420 to rotate. Under the action of the connecting rod 200, the driving wheel 410, the sliding sleeve 210 and the connecting rod 200 realize the crank slider movement, and the connecting frame 220 realizes up and down reciprocating motion along the connecting rod 200. The right end of the outer wall of the driving shaft 140 is fixedly connected with a friction wheel 500, and the right side of the upper end of the outer wall of the mounting base 100 is welded with a mounting seat 2 510.

A reset spring 440 is fixedly connected between the sliding sleeve 210 and the mounting seat 201. The reset spring 440 can drive the connecting frame 220 to move upward and reset when the driving wheel 410 loses power.

At the same time, when the ore is stuck in the jaw crusher due to slipping, the hydraulic telescopic push rod 520 is started to slide upward, driving the intermediate wheel 530 to move upward, so that the intermediate wheel 530 and the driving wheel 410 are squeezed and contacted with the friction wheel 500 at the same time, so that the intermediate wheel 530 and the driving wheel 410 are transmitted to the friction wheel 500. The dynamic connection enables the friction wheel 500 to drive the driving wheel 410 to rotate through the intermediate wheel 530, and the crank 420 to rotate through the rotation of the driving wheel 410.

When the rotating iron plate 800 covers the oblique discharge port 620, it can be closed, so that the ore on the conveyor belt 610 cannot fall into the feed port 120 temporarily. The rotating sleeve 700 and the rotating rod 710 are rotatably connected to realize the rotating connection between the rotating iron plate 800 and the bevel discharge port 620. A connecting seat 810 is fixedly installed in the middle of the upper end of the outer wall of the rotating iron plate 800, and a rotating block 820 is rotatably connected inside the connecting seat 810.
